摘要
介绍了一种基于以太网PCM帧同步及数据合并解调器的设计与实现,选用Realtek公司生产的RTL8019AS以太网控制器作为接口芯片和Altera公司的FPGA作为控制器完成硬件设计,选择和裁剪TCP/IP协议并基于VHDL语言完成软件设计。该设计主要完成遥测接收系统中字帧的同步以及时统的建立,并通过以太网接口将数据存储到计算机中进行实时显示和事后处理。
A design and implementation of demodulator,including PC M frame synchronization and data consolidation base on ethernet network, is introduced. The hardware design is completed, which using the RTL8091 AS of Realtek corporation as the interface chip and FPGA of Altera corporation as the controller, and also completed the software design base on VHDL language by choosing and cutting out TCP/IP protocol. This design mainly completes word and frame synchronization and timing foundation of telemetry and receive systems, and storage data in computer by ethernet interface to real time display and deal with afterwords.
